Funny thing is .... pax from Habrbourfront to Sengkang , and pax from PSA Building side to Sengkang , both can actually go via different route .
Harbourfront surely will chose to go by either CTE or KPE tunnel .
PSA Building to Sengkang they actually or rather surely chose to go by Lornie then CTE .
Such a short distance differences , the route can be totally different .
